[SQLObject] orderBy reversed

[Philippe N. <sw...@fr...>]

Hi,

I have a little problem w/ orderBy keyword of MultipleJoin().  I have the
following class:

class Album(SQLObject):
     # [ ... ]
    albumObjects =3D
MultipleJoin('AlbumObject',orderBy=3D-AlbumObject.q.modificationDate)

And when i try to use it, i get:

File "/usr/lib/python2.3/site-packages/sqlobject/joins.py", line 87, in
sorter
   orderBy =3D orderBy[1:]\nexceptions.AttributeError: SQLPrefix instance
has no attribute '__getitem__'

And in fact there's no __getitem__ method in SQLExpression (from which
SQLPrefix inheritates).
If I replace -AlbumObject.q.modificationDate by '-modificationDate', it
works like a charm. Do you think it's a bug in the sqlbuilder module or
in joins.py ?
